Hi Ed,

I hope I can help with at least the Link of FUCHS, who makes Aerosave and Aerosynth:
http://www.fuchs.com/index.php
It has offices in USA and maybe would be even cheaper to get Aero Save and AeroSynth from them
even if Graupner or TowerHobbies do not carry them.
Here are also the locations of FUCHS in USA:
http://www.fuchs.com/fuchs_in_americas.php
Please NOTE: - I mixed Aerosave with Castor (3:1) and the results were DISASTER - hell of detonations !!!
Then Pe Reivers exlained that FUCHS warned about this and then Fuchs reccomends AeroSynth to be
mixed with Castor if one want to do that. Still Aerosave is for me about 6x more expensive than castor
and I use it only for last flight & conservation of the engine. Yes, I agree fully for the castor varnish
but you know sometimes with too much experiments with propellers (small ones and high RPM) the
things go easily out of control. Thus the "wash" of the last flight makes to me good sense and then
I do not care if I am going to fly next day or ... next year... Aerosave seems real safe ...

Cheers,
Nick

PS. It might turn out that Aerosave and AeroSynth are distributed only by Graupner.
I wander what is the case in USA; why do you say that they are not available ??
Still one can order directly rom Graupner or even better from www.lindinger.at;
have you tried any of those ?
